SAFETY-PIN.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed December 28, 1918. Serial No. 268,683.

To all whom it may concern:

Be it known that I, JOHN H. RICHARD- soN, a citizen of the UnitedStates, and a resident of San Pedro, in the county of Los Angeles andState of California, have inof the character specified, wherein means isprovided for locking the pin to the shield or clasp when the pm isclosed, to prevent displacement of the point of the pin from the shieldby strain upon the pin.

In the drawings:

Figure 1 isa perspective view of the improved pin;

Fig. 2 is a side view of the shield, with parts in section;

Figs. 3 and 4 are sections on the lines 33 and l4,'respectively, of Fig.2, each view looking in the direction of the arrows adjacent to theline.

In the present embodiment of the invention the improved pin comprises apair of arms 1 and 2,which are connected by an integral coil 3 formingthe spring which acts normally to force the freeends of the arms awayfrom each other. One of the arms is pointed, as indicated at 4:, andthis arm is the movable arm of the pin.

A shield or clasp 5 is connected with the arm 1, the said shield orclasp being of sheet metal of suitable weight. This shield or clasp issubstantially U-shaped, consisting of a body 5 and arms 6 and 7, andeach of the arms 6 and 7 is substantially channel shaped, as is also thebody 5, thechannels of the arms and body being continuous and facinginwardly. The arm 6 receives within its channel the outer end of the arm1, and the said arm is secured to the shield in any suitable manner, as,for instance, by brazing or soldering or the like. The other portion 7is adapted to receive the point of the arm 2, and the said portion 7 hasan upstanding tongue 8 at approximately the center, that is, midwaybetween the side walls, which is adapted to extend through a slot 9 inthe point of the pin. 7

This tongue extends to near the top of the side walls of the channel,and it will be noticed that the side walls of the channel of the portion6 have downward extensions Copies of this patent may be obtained forfive cents each, by addressing the Commissioner of Patents,

10 at about the location of the tongue 8, which serves to guide thepoint of the pin into the channel of the portion 7. The side walls ofthe channel of the portion 7 have guide extensions 11 at the outer sidesof the extensions 10. for guiding the point of the pin into the channeland into such position that the tongue will engage the slot. As shown,this tongue 8 is formed by striking up a portion of one wall of thechannel, that is, the tongue is cut out of the said wall and is bentinwardly midway between the walls, for the purpose specified.

It will be noticed that the sheath has a substantially channel shapedportion held in spaced relation to the arm to which the sheath issecured and with the channel facing the said arm and that the sheath hasan extension from the arm to which it is secured, extending between theside walls of the channel shaped portion of the sheath, and that each ofthe side walls of the channel shaped portion has an inturned portion atits free edge. The distance between the extension and the inturnedportion of each side wall is equal to the distance between the inturnedportions at the point where the pointed arm enters, so that the pointedarm is certainly guided into engagement with the tongue, without anypossibility of the pointed arm slipping between the tongue and the sidewalls.

I claim:

A safety pin comprising a pair of arms, one of said arms carrying asheath and the other being the piercing arm, said arm having a slot, andthe sheath a tongue for engagement by the slot when the plercing arm isin the sheath, said sheath having a substantially channel shaped portionheld in spaced relation to the arm to which the sheath is secured andwith the channel facing the said arm and having an extension from thesaid arm extending between the side walls of the channel shaped portionof JOHN HENRY RICHARDSON.
